Abstract

Способ извлечения металла из низкосортной руды, которую подвергают цианидному выщелачиванию, чтобы получить продуктивный раствор выщелачивания (ПРВ), содержащий цианид металла, который удаляют из ПРВ посредством ультрафильтрации и нанофильтрации, а затем подкисляют и сульфидируют, чтобы получить сульфид металла, из которого выделяют металл, и циановодород, который возвращают на стадию цианидного выщелачивания.The method of extracting metal from low-grade ore, which is subjected to cyanide leaching, to obtain a productive leaching solution (PRV) containing metal cyanide, which is removed from the PRV by ultrafiltration and nanofiltration, and then acidified and sulphidized to obtain a metal sulfide, from which the metal is separated, and hydrogen cyanide, which is returned to the cyanide leaching stage.
